    3. Locate and delete the registry key named {B54F3741-5B07-11CF-A4B0-00AA004A55E8}.
        We recommend making a backup of this registry key before deleting it.
    4. Close the registry editor.
    5. Go back to the command prompt window you used in the instructions above.
        If you closed this window, follow steps 1 - 4 above to open the command prompt window using the Run as Administrator option and navigate to the C:\Windows\System32 directory.
    6. Within the C:\Windows\System32 directory, type regsvr32 C:\Windows\System32\vbscript.dll and then press Enter.
    7. You will receive a message that says, "DLLRegisterServer in C:\Windows\System32\vbscript.dll succeeded." Click OK.
    8. Close the command prompt window.

You can now install Cisco VPN client.
